Nature & Science
Today Sunset Crater Volcano National Monument protects 3040 acres representing the Colorado Plateau’s most recent volcanic eruption. It is the youngest, least-eroded cinder cone in the San Francisco Volcanic Field. Much of the ground surface is covered by lava flows or deep volcanic cinder deposits; at first glance, the landscape still appears stark and inhospitable. But look again - within the dramatic geologic features are small islands of pine and aspen trees, desert shrubs, and wildflowers. These provide small but unique habitats for wildlife as well. Slowly but surely, life returns.
The significance of Sunset Crater Volcano National Monument extends beyond the geological events themselves. The powerful geologic processes that formed the volcano profoundly affected the way of life of local inhabitants during the 11th and 12th centuries and forever changed both the landscape and the ecology of the area. This volcano and its relatively undeveloped landscape provide an unparalleled opportunity to study plant succession and ecological change in an arid volcanic landscape.
Did You Know?
Sunset Crater was nearly dynamited in 1929, to create a landslide for the Hollywood movie "Avalanche". Local citizens were outraged and lobbied for its protection. The result was establishment of Sunset Crater National Monument in 1930. "Volcano" was added to the name in 1990.
